Problems solved by technology

[0002] With the rapid development of heterogeneous networks, that is, networks where IPv4 networks and IPv6 networks coexist, mobile nodes (MN, Mobile Node) with multiple interfaces to access heterogeneous networks, such as multi-mode terminals, are becoming more and more popular. However, when MN When accessing a heterogeneous network, related technologies have no effective solution for how to use the multi-interface access capability of the MN to improve the efficiency and flexibility of service data transmission

Embodiment 1

[0075] The first preferred implementation mode of the above-mentioned embodiment of the present invention specifically includes the following steps:

[0076] (1) MN establishes a tunnel

[0077] In order to switch the data packet corresponding to the UDP service flow with the destination port number 1234 to eth0 for transmission, the MN establishes an IPv6tn1 tunnel from eth0 to HA, specifically:

[0078] The MN uses the Linux built-in extensible function framework XFRM to generate the XFRM policy (policy) corresponding to the IPv6tn1 tunnel, and uses the XFRM policy to match the data packet corresponding to the UDP service flow entering the IPv6tn1 tunnel with the destination port number of 1234. In the XFRM policy The XFRM template (template) saves the information of the IPv6 header that encapsulates the matched data packet. The source address of the IPv6 header is the entry address of the IPv6tn1 tunnel, that is, the care-of address CoAv6 of eth0, and the destination addres...

Abstract

The invention discloses a method, equipment and a system for managing services of an IPv4 / IPv6 (internet protocol version 4 / internet protocol version 6). The method comprises the following steps of establishing a tunnel from a first network interface of an MN (mobile node) to a HA (home agent); accessing a head part based on UDP (user data protocol) and a first network interface of the MN into the head part of the network corresponding to IP (internet protocol), and packaging a data packet of services of a second network interface which is accessed into the MN; sending the packaged data packet to the HA through a channel from the first network interface of the MN to the HA. By adopting the technical scheme, the method has the advantages that the band width resource of the network interface of the MN is sufficiently utilized, the transmission efficiency of the service data is improved, and the flexibility is high.

Description

technical field [0001] The present invention relates to Internet technology, in particular to a method, device and system for managing Internet Protocol version 4 / Internet Protocol version 6 (IPv4 / IPv6, Internet Protocol version4 / Internet Protocol version6) services. Background technique [0002] With the rapid development of heterogeneous networks, that is, networks where IPv4 networks and IPv6 networks coexist, mobile nodes (MN, Mobile Node) with multiple interfaces to access heterogeneous networks, such as multi-mode terminals, are becoming more and more popular. However, when MN When accessing a heterogeneous network, there is still no effective solution in related technologies for how to utilize the multi-interface access capability of the MN to improve the efficiency and flexibility of service data transmission. Contents of the invention [0003] In view of this, the main purpose of the present invention is to provide a method, device and system for managing IPv4 / IPv...
